Enum VersioningBehavior

Namespace
Temporalio.Api.Enums.V1
Assembly
Temporalio.dll

Versioning Behavior specifies if and how a workflow execution moves between Worker Deployment Versions. The Versioning Behavior of a workflow execution is typically specified by the worker who completes the first task of the execution, but is also overridable manually for new and existing workflows (see VersioningOverride). Experimental. Worker Deployments are experimental and might significantly change in the future.

public enum VersioningBehavior

Fields

[OriginalName("VERSIONING_BEHAVIOR_AUTO_UPGRADE")] AutoUpgrade = 2

Workflow will automatically move to the Current Deployment Version of its Task Queue when the next workflow task is dispatched. AutoUpgrade behavior is suitable for long-running workflows as it allows them to move to the latest Deployment Version, but the user still needs to use Patching to keep the new code compatible with prior versions for changed workflow types. Activities of AUTO_UPGRADE workflows are sent to the Deployment Version of the workflow execution (as specified in versioning_info.version based on the last completed workflow task). Exception to this would be when the activity Task Queue workers are not present in the workflow's Deployment Version, in which case, the activity will be sent to a different Deployment Version according to the Current Deployment Version of its own task queue. Workflows stuck on a backlogged activity will still auto-upgrade if the Current Deployment Version of their Task Queue changes, without having to wait for the backlogged activity to complete on the old Version.

[OriginalName("VERSIONING_BEHAVIOR_PINNED")] Pinned = 1

Workflow will start on the Current Deployment Version of its Task Queue, and then will be pinned to that same Deployment Version until completion (the Version that this Workflow is pinned to is specified in versioning_info.version). This behavior eliminates most of compatibility concerns users face when changing their code. Patching is not needed when pinned workflows code change. Can be overridden explicitly via UpdateWorkflowExecutionOptions API to move the execution to another Deployment Version. Activities of PINNED workflows are sent to the same Deployment Version. Exception to this would be when the activity Task Queue workers are not present in the workflow's Deployment Version, in which case the activity will be sent to the Current Deployment Version of its own task queue.

[OriginalName("VERSIONING_BEHAVIOR_UNSPECIFIED")] Unspecified = 0

Workflow execution does not have a Versioning Behavior and is called Unversioned. This is the legacy behavior. An Unversioned workflow's task can go to any Unversioned worker (see WorkerVersioningMode.) User needs to use Patching to keep the new code compatible with prior versions when dealing with Unversioned workflows.
